Terrarium pop-up plant ID?

[Myrtle]

Hi, I've just spotted these small umbrellas in my terrarium and wondered if anyone knew what they were? They look a bit like the umbrellas associated with liverworts, but I can't find one similar... They're a good cm in diameter.

Hi all,

I've just spotted these small umbrellas in my terrarium and wondered if anyone knew what they were?

Might they be "leaves" <"Journal - Hermetosphere">?

This is Utricularia pubescens.

Ooh, quite possibly! I was looking at liverworts and didn't think of utricularia. Finally one I can grow! Huzzah!

They're a good cm in diameter.

This is what throws me off a bit, at least afaik or have seen the Utricularia pubescens don't grow leaves this large. I'm growing it for a few years now and it always stays rather tiny with leaves a few mm in size. If it's a Utricularia it might be U. nelumbifolia that grows a lot bigger and it will grow a kind a horseshoe-shaped leaf when it matures.

Utricularia nelumbifolia

Utricularia Nelumbifolia X reniformis is a known cultivar in the terrarium trade.

I've just measured them as I didn't trust my measurement by eye and they're def 9mm in diameter.
